Full Metal housing and metal gears! much more quieter than stock plastic one.Good turning speed for Modern tank, and also slow enough for WWII tanks!See below video for reference.

Now one more choice faster turret rotation, it's good for modern tank with stablization system like Clark TK60G3/G2 system.

Simply direct replace stock one.

! Do not block the rotation when rotating with these fast speed rotation gearbox, if rotation blocked will generate high current during blocking and may cause damage on the tank control board, please be remind and take notice, used at your own risk. we will not response to any damage during this case.
